Hello,
On 1 domain controller running Windows 2003 sp2 the event log is full of dns errors Event Id:7050. I enabled dns logging on the server and found this:

The error in the event log shows that it happened at 07:05:27.

thanks.
When an inbound email arrives, the sender and/or urls listed in the email are checked against realtime blacklists. In this case it looks like bl.spamcop.net and sbl-xbl.spamhaus.org.
